Molecular Structure and Geometry

Learners practice drawing Lewis dot structures, build molecules with model kits, and predict molecular shapes using VSEPR theory. The combination of written work and hands-on reinforcement benefits young scientists.

A model is worth a thousand words. Young scholars use what they know about the structure of hydrocarbons to build Lewis dot structures and molecular models. Their tasks include multiple bonds, geometric hybrids, and various isomers.

In this drawing Lewis structures worksheet, students read about the 5 steps taken to draw Lewis structures for atoms and molecules. These include identifying the valence electrons, placing pairs of electrons between atoms to be bonded,...

Of quartz I love geology! The chapter offers five activities at three different levels. It features hands-on activities that cover crystal shapes, cleavage and fracture, hardness scale, specific gravity, and mineral...

The VSEPR Model of molecular structure is exhibited through this series of slides. The step-by-step process is listed, and then examples are provided. The graphics give a visual display of the spatial relationship between the atoms of...

Ready to take molecules out of the two dimensional world and into 3-D? Chemistry scholars explore molecular geometry through a well-written video from the JFR Science series. Topics include the effects of bonding and non-bonding...

Tutorial outline weaves together resource links which instruct the learner in drawing Lewis dot structures. A pre- and post-quiz are provided, as well as visuals, questions with immediate feedback, and a reading list to help students...

How is a molecule's shape determined? Explore bond angles, lone pairs, and VSEPR theory through a logic-based activity. Chemists pull together information about the major molecular shapes, then use it to solve puzzles.

Ready to introduce the realities of molecular geometry to chemistry pupils? Use a logic-based interactive! Perfect as individual practice, the puzzles explore the bond angles and repulsions present in three common molecular shapes.

In this interactive activity from ChemThink, students will learn about covalent molecules and how the VSEPR theory predicts the shapes of covalently-bonded molecules.
